I'm help a friend out that just bought a 2008 Specialized Roubaix Expert with Rival brakes, less than 30 miles on this bike so far. There are a number of tar and gravel roads in our area. Gravel gets caught in the front brake & heavily rubs the tire. The tire seems way too close to the brake and you can see in the underside shot, pea size gravel is grinding away at the underside of the fork. Plenty of clearance for the back brake. Any suggestions would be helpful. I would appreciate any help you can give.
